US Company Formation for Founders in the UK, Canada, Australia, and the EU

Founders in the United Kingdom, Canada, Australia, New Zealand, and the EU often want the same US LLC filing. The secretary-of-state steps really are similar. What changes is the life you already have: tax residency, how you talk about consumption tax, which banks will open an account remotely, and whether a local company already exists that should own the US entity. This is one guide to those differences, not a cloned page per country.

Scriplit is not a law firm or a CPA firm. This article is general information, not legal, tax, or immigration advice. Confirm current IRS, HMRC, CRA, ATO, IRD, and EU member-state rules. A US LLC does not guarantee banking, Stripe, visas, or tax outcomes, and it does not move your tax residency by itself.

The US filing is the shared part

Name, registered agent, state articles, operating agreement, EIN application — that sequence is the same whether you live in Manchester, Toronto, Melbourne, Auckland, or Lisbon. Read how to form a US LLC as a non-resident for the mechanics. The rest of this article is about not treating the LLC as a second passport or a VAT loophole.

You remain a tax resident of the place that actually taxes your worldwide income, unless you have changed residence under that place’s rules. A Wyoming stamp does not end UK self-assessment, Canadian T1/T2 filings, Australian tax residency, NZ tax residency, or EU domestic tax. Treat the LLC as extra documentation and possibly extra US information returns, not as an automatic territorial reset.

Tax residency vs the company’s home state

US state of formation answers “which US office you file annual reports with.” Tax residency answers “which government taxes you as a person.” Those can point at different maps.

• United Kingdom: You may still be UK resident and domiciled (or deemed so) for income tax and, where relevant, corporation tax if you also run a UK limited company. Controlled foreign company and transfer-pricing ideas can appear if the UK company and the LLC transact. Do not assume “US LLC, so not UK.” HMRC looks at where management happens and where you live.
• Canada: Canadian residents report worldwide income. A US LLC may be a foreign affiliate or other reporting category depending on facts. CRA forms for foreign property and affiliates are easy to miss if you only copied a US blog.
• Australia: Tax residency of the individual and of any Australian company you already own matters. The ATO will not ignore a US entity you control from Sydney because the articles say Cheyenne.
• New Zealand: Similar theme: IRD cares about your residence and control. A US company is foreign, not invisible.
• EU member states: Rules diverge. Some founders already have a local GmbH, SAS, or BV. Parking IP or contracts in a US LLC while you live and work in the EU can create permanent-establishment and CFC-style questions. Get local advice before you shift customer contracts.

Double-tax treaties exist between the US and many of these countries. Treaties do not file themselves. They also do not erase information-return penalties if you were supposed to file a US form and did not.

VAT, GST, and “sales tax” are not the same vocabulary

In the UK and EU, VAT is a registration and invoicing system with VAT numbers, reverse charge, and digital-services rules that may already apply to you. Australia and New Zealand use GST. Canada uses GST/HST (and QST in Québec). The United States uses state and local sales tax, often collected by marketplaces, with economic-nexus thresholds that are not a VAT ID.

Practical translation problems:

• A US customer’s “no VAT on this invoice” does not mean you skip UK VAT on a B2C digital sale into the UK if UK rules still catch you.
• Charging US sales tax on a checkout built for VAT-inclusive prices will confuse everyone. Pick a tax engine that knows which regime you are in for which SKU and customer location.
• Your US LLC’s EIN is not a VAT number and not a GST number. Do not put it in the VAT field of an EU invoice.

If you already file VAT/GST at home, adding a US storefront is an extra regime, not a replacement. Marketplace facilitator laws in US states may collect sales tax for you on Amazon or similar; that does not automatically settle VAT in Europe.

Banking and processors from high-income English-speaking countries

UK, Canadian, Australian, and NZ passports often have an easier time with remote KYC than passports from countries with heavier fraud controls — and they still get declined. EU founders vary by bank and by whether they already have a local IBAN and a local Stripe account that already works.

Common patterns (not promises):

• Some founders keep a local Stripe or bank for local customers and add a US Stripe account later for USD enterprise deals. Two accounts means two payouts and two tax stories. Document why both exist.
• US fintech banks still want formation docs, EIN letter, and a site that matches. A UK Ltd already in good standing does not replace those if the applicant is the LLC.
• Wise, Payoneer, and similar services are not “the US bank account” on every processor’s list. Check the processor’s payout destinations before you plan around a multi-currency wallet.

Currency: invoicing in USD through a US LLC while you live on GBP, CAD, AUD, NZD, or EUR creates FX in your personal life. That is bookkeeping, not a formation feature.

Existing local companies

If you already have a Ltd, Pty Ltd, or EU company, decide whether the US LLC is a subsidiary, a sister company with the same humans as members, or a replacement. Each choice has tax and contract-migration work. Moving customer relationships from a UK Ltd to a Wyoming LLC is not a settings toggle; it is novation, VAT, and sometimes customer consent.

Directors’ duties at home do not disappear because you opened a US entity. Using the LLC to strip a local company of value without advice is how you meet a different kind of professional: a litigator.

A single checklist that works in all of these places

1. Write where you are tax resident and whether a local company already owns the business.
2. List where customers are (UK, EU, US, AU, etc.) and which consumption-tax systems you already file.
3. Form the US LLC only if a US identity, bank, or contract actually requires it — then follow the non-resident filing sequence.
4. Apply for an EIN when banking or the IRS process needs it; do not expect a same-week miracle.
5. Tell your home-country accountant that the LLC exists before year end, not after a penalty letter.

Scriplit can help with the US filing and EIN mechanics via US LLC formation. We do not replace HMRC, CRA, ATO, IRD, or EU tax advisers. If you contact us, mention your country of residence and whether a local company already exists so we do not treat a UK founder and an EU founder as identical beyond the Wyoming form. The form is the easy part. The map of tax authorities is the part that differs.
